Unlikely Survivors: The Remarkable Adaptation of Asian Honeybees in Australia


Unlikely Survivors: The Remarkable Adaptation of Asian Honeybees in Australia




In an astonishing display of resilience and adaptability, the Asian honeybee, a species once considered unlikely to thrive due to its limited genetic diversity, has established a burgeoning population in North Queensland, Australia. This revelation, detailed in a study published in Current Biology, challenges long-standing assumptions about biodiversity and adaptability, offering new perspectives on conservation and the management of invasive species.

Led by Dr. Rosalyn Gloag of the University of Sydney, the research not only charts the impressive expansion of the Asian honeybee but also provides a comprehensive genetic timeline that traces the population's evolution from its arrival in 2007. Initially perceived as a threat due to potential parasites, the bees have since been recognized for their extraordinary capacity to adapt, flourishing in a new habitat without carrying the dreaded varroa mite, a notorious pest that poses significant risks to bee populations worldwide.

This case study's significance extends far beyond the fields of Cairns. It serves as a critical examination of how species respond to environmental pressures and adapt to new ecosystems. The findings underscore a hopeful notion: even populations that undergo dramatic declines in genetic diversity can find ways to survive and adapt in the face of climate change and other ecological challenges.

For environmental activists and concerned citizens, the story of the Asian honeybee in Australia is a complex narrative that intertwines the challenges of managing invasive species with the broader themes of resilience and conservation. It prompts us to reconsider our understanding of ecological balance and the capacities of species to overcome adversities, perhaps offering lessons on how we might support threatened species and ecosystems in an ever-changing world.

As we navigate the implications of climate change and human impact on natural habitats, the adaptability of the Asian honeybee stands as a testament to the unpredictability of nature and the potential for unexpected outcomes in conservation efforts.


 

Frequently Asked Questions (FAQ):

  1. What is a genetic bottleneck and how did the Asian honeybees overcome it? A genetic bottleneck occurs when a new population starts with a limited number of individuals, resulting in reduced genetic diversity. The Asian honeybees overcame this by rapidly adapting to their new environment in North Queensland, despite the low genetic diversity.

  2. Why is the study of Asian honeybees in Australia important? The study provides insights into how species can adapt to new environments and the implications for biodiversity and conservation, especially in the context of climate change and invasive species management.

  3. What challenges do Asian honeybees pose to the Australian environment and biosecurity? The bees are considered invasive and could carry parasites, posing threats to local ecosystems and the domestic honey industry. However, the study found that the bees did not carry the varroa mite, a major concern for biosecurity officials.

  4. How did the researchers study the bee population's adaptation? They re-sequenced entire genomes of 118 bees collected over a decade, providing a unique opportunity to observe natural selection and adaptation in a population with initially low genetic diversity.

  5. What implications does this research have for other species facing environmental changes? It suggests that species with low genetic diversity can still adapt rapidly to changing conditions, offering potential insights for conservation strategies and resilience against climate change and other disturbances.

Non-contact exposure to dinotefuran disrupts honey bee homing by altering MagR and Cry2 gene expression

  Non-contact exposure to dinotefuran disrupts honey bee homing by altering  MagR  and  Cry2  gene expression Dinotefuran is known to negatively affect honeybee ( Apis mellifera ) behavior, but the underlying mechanism remains unclear. The magnetoreceptor ( MagR , which responds to magnetic fields) and cryptochrome ( Cry2 , which is sensitive to light) genes are considered to play important roles in honey bees’ homing and localization behaviors. Our study found that dinotefuran, even without direct contact, can act like a magnet, significantly altering  MagR  expression in honeybees. This non-contact exposure reduced the bees’ homing rate. In further experiments, we exposed foragers to light and magnetic fields, the  MagR  gene responded to magnetic fields only in the presence of light, with  Cry 2 playing a key switching role in the magnetic field receptor mechanism ( MagR–Cry2 ). Yeast two-hybrid and BiFc assays confirmed an interactio...

New Report – Interlocked: Midwives and the Climate Crisis

New Report – Interlocked: Midwives and the Climate Crisis Earlier this year, midwives from 41 countries shared their experiences of working in communities affected by climate change through our survey, Midwives’ Experiences and Perspectives on Climate Change. Their voices shaped our new report, Interlocked: Midwives and the Climate Crisis , which highlights how midwives are already responding to the health impacts of climate disasters like floods, wildfires, and extreme heat—and why they must be included in climate action plans. What did we learn?Climate change is damaging community health: 75% of midwives reported that climate change is harming the communities they serve, with rising rates of preterm births, food insecurity, and restricted access to care during disasters like floods. Midwives are critical first responders: Midwives are often the first and only healthcare providers on the ground in crises, delivering care during wildfires, floods, and extreme heat. Midwives face signi...

Bee attack claims life of newspaper distributor

  Bee attack claims life of newspaper distributor Newspaper distributor Pushparaja Shetty (45), who sustained severe injuries in a bee attack, succumbed to his injuries on Thursday at a hospital in Mangaluru. Pushparaja was attacked by a swarm of bees on Wednesday morning while walking at Kenjaru Taangadi under Bajpe town panchayat limits. He was immediately admitted to a hospital for treatment but could not survive the ordeal. Fondly known as ‘Boggu’ in the Porkodi area, Pushparaja was well-known for his dedication to delivering newspapers on foot to every household. He was admired for his generosity, as he often distributed sweets to schoolchildren on Independence Day using his own earnings and contributed part of his income to the betterment of society. Pushparaja was unmarried and is survived by three brothers and one sister.

“Global honey crisis”: Testing technology and local sourcing soars amid fraud and tampering concerns

  “Global honey crisis”: Testing technology and local sourcing soars amid fraud and tampering concerns The World Beekeeping Awards will not grant a prize for honey next year due to the “inability” to thoroughly test honey for adulteration. The announcement comes amid the rise of honey fraud in the EU, where a 2023 investigation found that 46% of 147 honey samples tested were likely contaminated with low-cost plant syrups.  Apimondia, the International Federation of Beekeepers’ Associations, organizes the event at its Congress, whose 49th edition will be held in Copenhagen, Denmark, in September 2025. The conference brings together beekeepers, scientists and other stakeholders. “We will celebrate honey in many ways at the Congress, but honey will no longer be a category, and thus, there will be no honey judging in the World Beekeeping Awards. The lessons learned from Canada 2019 and Chile 2023 were that adequate testing was impossible if we are to award winning honey at the Con...

Start the New Year Humming Like a Bee

  Start the New Year Humming Like a Bee There are lots of opportunities to be as busy as a bee during these winter holidays. As we hustle toward the dawn of the New Year, it can be hard to notice that the natural world is actually suggesting something different for us right now. We’re past the solstice, but the winter still stretches ahead, the days are still short and the nights long. We’re being invited into a quieter, more inner-focused time. The ancient yogis were all about this inner focus. In India, for example, the Upanishads, the Sanskrit writings that accompanied the development of Hinduism — and alongside it, yoga — beginning around 800 B.C.E., went deeper than earlier texts had into philosophy and questions of being. With the goals of increased inner awareness and higher consciousness, yoga was at that time not yet as focused on the body or on asanas, as it now can tend to be. But the yogis did develop many practices to try to open the way to those goals. They discovered...

The Essential Role of Bees in Our Ecosystem and the Challenges They Face

The Essential Role of Bees in Our Ecosystem and the Challenges They Face Bees have been an integral part of our ecosystem and human agriculture for over four centuries, primarily utilized for their honey in the early days. Now, they are recognized more for their critical role in pollination, which directly impacts a vast majority of the food we consume. Mark Lilly, a prominent beekeeper, emphasizes that without bees' pollination efforts, a significant portion of our diet would be at risk. However, bees face numerous threats, including varroa mites and, in specific regions like West Virginia, black bears. These challenges necessitate concerted efforts for preservation and protection. Frequently Asked Questions (FAQs) Q1: Why are bees so important to the ecosystem? A1: Bees are crucial for pollinating plants, which is necessary for the production of fruits, vegetables, and nuts. Without bees, a large portion of the food we eat would not be available. Q2: What are the main threats to...

The Growing Dilemma of Pet Burials in South Korea: Environmental and Legal Hurdles

The Growing Dilemma of Pet Burials in South Korea: Environmental and Legal Hurdles As the number of pets in South Korea steadily increases, pet owners face a growing dilemma due to the limited number of pet cemeteries across the country. Under the current legal framework, pet remains are classified as household waste, requiring specific disposal methods that are neither convenient nor easily accessible for all citizens. The imbalance between the rising pet population—over 5.52 million households with pets by the end of 2022—and the mere 70 registered pet cemeteries has led to significant challenges. This shortage is particularly evident in regions like Jeju Island, where pet owners must undergo arduous journeys to the mainland to ensure their pets receive proper burials. The root cause of this shortage lies in the strict regulations governing the establishment of pet cemeteries. These facilities, which must include crematoriums, face numerous restrictions, such as proximity to resident...

Climate Crisis Claims Glacier's Vital Climate Data Archive

  Climate Crisis Claims Glacier's Vital Climate Data Archive A recent study published in Nature Geoscience reveals a distressing consequence of global warming: the irreversible loss of valuable climate data stored in alpine glaciers. The research, conducted by a team led by Margit Schwikowski from the Paul Scherrer Institute (PSI), underscores the alarming rate at which glaciers are melting and highlights the implications for climate research. The study focuses on the Corbassière glacier at Grand Combin in Switzerland, where ice cores drilled in 2018 and 2020 were intended to serve as vital climate archives. However, comparing the two sets of ice cores reveals a grim reality—global warming has rendered the glacier unsuitable as a reliable climate archive. Glaciers, renowned as climate archives, encapsulate valuable information about past climatic conditions and atmospheric compositions. The fluctuating concentrations of trace substances in ice layers provide insights into historica...

German election: Climate and environment take a back seat

  German election: Climate and environment take a back seat When the coalition government comprising the center-left  Social Democratic Party (SPD) ,  Greens  and neoliberal  Free Democratic Party (FDP)  emerged after the last German federal election in the fall of 2021, then-incoming Chancellor  Olaf Scholz  (SPD) did not object to being called the "climate chancellor." That was no surprise: the climate crisis had been a top issue during the election campaign. The new government made the fight against climate change a task for the Economy Ministry and appointed Vice Chancellor  Robert Habeck  from the Greens as its head. Three and a half years later, campaign speeches barely mention climate protection. The dominant issues are how to curb irregular immigration and how to boost Germany's sluggish economy. Skeptical view of renewable energy The head of the center-right  Christian Democratic Union (CDU) ,  Friedrich Merz ...
